连续形状波导中自旋相关的电子输运

Spin-dependent electron transport in waveguide with continuous shape

Yue Ban, E. Ya. Sherman

摘要:

研究了自旋轨道耦合下二维波导形状对自旋相关电子输运的影响。如果波导具有收缩,则可以通过调制自旋-轨道耦合的强度来控制从经典运动到隧穿状态的过渡。自旋旋进强烈地依赖于波导的形状。

英文摘要:

We study effects of the shape of a two-dimensional waveguide on the spin-dependent electron transport in the presence of spin-orbit coupling. The transition from classical motion to the tunneling regime can be controlled there by modulating the strength of spin-orbit coupling if the waveguide has a constriction. The spin precession strongly depends on the shape of the waveguide.
